What customers say

Based on genuine customer reviews

Septic tank servicing, sewage treatment plant installation and pump replacement form the core of what customers describe at Drain & Tank Engineering, with Dean repeatedly identified as the person who resolves faults that others have struggled to diagnose. A complicated water supply problem is remembered as a turning point, solved only after other firms had failed, and the same account notes a follow-up call some weeks later to confirm that the repair had held. Prompt arrival, courteous staff and immaculate workmanship recur across the feedback.

Several customers highlight tank and blower maintenance carried out efficiently and without mess, and the engineers are described as fully equipped and knowledgeable for the task. The advice given is praised as honest and accurate, with one customer welcoming a fair report rather than pressure towards an expensive replacement system. Sewage treatment plants installed by the firm are said to have run reliably for years, needing only a replacement pump that was fitted without fuss. Dean and his son are named for completing a new water treatment plant quickly on a difficult job, and a rapid call-out is credited with saving a local club ahead of its ale festival.

I had a problem recently with my drains but also a very complicated problem with my water supply. I had several companies to look at the work and no one could work it out apart from Dean. He is extremely knowledgeable, reliable and hard working. He didn’t leave us until he was absolutely sure everything was working properly and he even phoned a few couple of weeks later to check that everything was ok. A couple of months later we seemed to have a slight drop in our water pressure and he arrived the next day to adjust it for us. I would definitely recommend Dean to anyone with drainage problems !!

At last I have found a company who will give honest and accurate advice rather than just trying to make me buy the most expensive system they can. The report was very fair. Thank you Drain & Tank Engineering.

Dean and his son worked very quickly and efficiently to install our new water treatment plant on what was not an easy job.

They installed our sewage treatment plant, which has worked well for over five years, just needing a new pump which was fitted promptly and without a problem.
